Amaral & Roeper's Multiple Grammars (MG) proposal offers an appealingly simple way of thinking about the linguistic representations of bilingual speakers. This article presents a commentary on the MG language acquisition theory proposed by Luiz Amaral and Tom Roeper in this issue, focusing on the theory's implications for child…

In English the nonfinite form is simply a bare verb, but in languages with a morphological distinction it usually takes the form of an infinitive. During the relevant stage the child, unlike an adult, sometimes uses an infinitive as the main verb of a root clause. Luigi Rizzi and certain other researchers therefore favor the term "root…

This article presents the authors' comments on Nina Hyams' article, "The Acquisition of Inflection: A Parameter Setting Approach" (AIPSA). The article began as a 1986 presentation at the Boston University Conference on Language Development (BUCLD). Parts of it were also presented at the 4th Eastern States Conference on Linguistics (ESCOL) in 1987…

Passives has been the focus of much research in language acquisition since the 1970s. It has been clear from this research that young children seldom produce passives spontaneously, particularly "long" or "full" passives with a by-phrase; and they usually perform poorly on experimental tests of the comprehension of passives, especially passives of…

McCormack and Hoerl's state of the art review of the development of temporal concepts from the end of infancy to the end of the fifth year shows that young children's conception of time is quite different from that of adults. Adults and 5-year-old children can construe an event from a range of temporal perspectives and can describe it from a…

The five papers in this issue cover a range of perspectives on the acquisition and use of the Spanish copulas "ser" and "estar" in a variety of contexts, including language contact, bilingual language acquisition, and classroom second language learning. The fact that these papers cite work in this area as far back as the early part of the 20th…

Describes American Sign Language (ASL) as "locative," because its grammatical/semantic structures derive from spatial notions; and "semantically perspicuous," because its phonetic and semantic structures are isomorphically related. Presents an ASL morphology showing how verbs are built from six basic locative/directional stems. Discusses…

Argues against Youssef's treatise which pointed out some difficulties in attempting to test Bickerton's language bioprogram hypothesis (LBH), contending that the treatise seriously misunderstood certain key concepts of the LBH and dismissed with questionable reasoning some important findings which supported the state/process distinction as a…

Within child language acquisition research, there has been a fair amount of controversy regarding children's knowledge of the grammatical properties associated with verbal inflection (e.g., tense, agreement, and aspect). Some researchers have proposed that the child's early grammar is fundamentally different from the adult grammar, whereas others…

The familiar linguistic diagram for language acquisition is held to be theory-neutral. Arguments of Lightfoot to the contrary are refuted, and theories about children's language acquisition are discussed. (Contains 11 references.) (LB)

Describes the cornerstone of traditional descriptive grammars as the construction (a recurrent patterns of linguistic elements that serves a communicative function), examining argument structure constructions, verbs and constructions, and implications for studying language development. Discusses Adele Goldberg's recent book, which develops the…

Presents the responses of 12 authors to Michael Tomasello's essay, which comments on Adele Goldberg's recent book, "Constructions: A Construction Grammar Approach to Argument Structure." Goldberg's book develops the theory of construction grammar for a set of problems associated with verb-argument structure. (SM)

Responds to 12 commentators who commented on an essay by the author about Adele Goldberg's recent book, "Constructions: A Construction Grammar Approach to Argument Structure," which develops the theory of construction grammar for a set of problems associated with verb-argument structure. (SM)

In a recent paper [Lidz, J., Gleitman, H., & Gleitman, L. (2003). Understanding how input matters: Verb learning and the footprint of universal grammar. "Cognition," 87, 151-178], we provided cross-linguistic evidence in favor of the following linked assertions: (i) Verb argument structure is a correlate of verb meaning; (ii) However, argument…

Argues that the data used to claim that morphosyntactic development of Italian-speaking children are inconsistent with nativist, parameter-setting models of language development is irrelevant to the specific hypothesis being evaluated. (25 references) (JL)
